How to Remove an Inflation Nozzle (Balloon Inflator)

To remove a regulator from a helium tank:

1. Make sure to close the cylinder valve by turning it to the right. 
2. Then you must release pressure from the inflator by depressing the nozzle as if you are filling a balloon. You will hear some gas release. If the gas release does not stop quickly– the cylinder is not closed.
3. Then unscrew the hand-tight connection and remove the inflator from the cylinder. 

See the link below to learn how to use the helium tank with both the latex and foil regulator nozzle and how to remove it safely.
